[산업상 이용분야][Industrial use]

본 고안은 전기로용 히팅 엘리먼트(ELEMENT)에 관한 것으로서, 보다 상세하게는 고온에서 장시간 사용하여도 엘리먼트의 변형이 일어나지 않도록 하는 히팅 엘리먼트에 관한 것이다.The present invention relates to a heating element (ELEMENT) for an electric furnace, and more particularly to a heating element that does not cause deformation of the element even after long-term use at high temperature.

[종래 기술][Prior art]

일반적으로 금속제의 부품이나 소재는, 소재의 특성을 변화시키기 위한 수단으로 열처리를 행하게 된다.Generally, metal parts and materials are subjected to heat treatment as a means for changing the properties of the materials.

열처리는 금속의 성질을 변화시켜 경화시키거나, 또는 반대로 연화시킬 수 있는 작업이며, 또 열간 가공성을 좋게 하며 최대의 내식성을 얻기 위하여 행하는 열처리도 있다.The heat treatment is a work that can be hardened by changing the properties of the metal, or vice versa, and there is also a heat treatment performed to improve hot workability and to obtain maximum corrosion resistance.

이러한 열처리를 행하는 전기로는 전류의 열효과를 이용하고 있는데, 금속을 용융점 이하로 가열하기 위하여 히팅 엘리먼트를 필수 구성 요소로 갖추고 있다.The electric furnace which performs such heat processing utilizes the thermal effect of an electric current, but is equipped with a heating element as an essential component in order to heat a metal below melting point.

상기한 히팅 엘리먼트는 전원이 인가되면 발열하는 열선을 복수개 갖추고 있는데, 이 열선들은 U자상으로 연속하여 연장되면서 대략 원통 형상을 이루며 배치된다.The heating element includes a plurality of heating wires that generate heat when power is applied, and the heating elements are arranged in a substantially cylindrical shape while continuously extending in a U shape.

이러한 형상으로 열선으로부터 나오는 열이 주위에 균일하게 퍼지게 되므로서 전기로 내의 온도를 일정하게 상승시키게 된다.In this shape, the heat from the hot wire is spread evenly around, thereby raising the temperature in the electric furnace uniformly.

[고안이 해결하려는 문제점][Problem trying to solve]

그러나 상기한 히팅 엘리먼트는, 열선들의 양측단을 지지하기 위한 수단을 강구하지 않고 있기 때문에 약 1000℃ 정도로 온도가 상승되는 경우 열변형을 일으켜 인접한 열선과 접촉하여 쇼트가 일어나게 된다.However, since the heating element does not devise a means for supporting both ends of the heating wires, when the temperature rises to about 1000 ° C., the heating element causes thermal deformation and short-contact with adjacent heating wires.

이러한 열변형에 따른 쇼트는 히팅 엘리먼트의 기능을 저하시키게 되므로 전기로 내의 온도 상승에 나쁜 영향을 주고 있다.The short caused by the heat deformation deteriorates the function of the heating element and thus adversely affects the temperature rise in the electric furnace.

[문제점을 해결하기 위한 수단][Means to solve the problem]

본 고안은 상기한 바와 같은 종래 기술의 문제점을 해소하기 위하여 안출된 것으로서, 본 고안의 목적은 고온에서도 열변형을 일으키지 않도록 하는 전기로용 히팅 엘리먼트를 제공하는데 있다.The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to provide a heating element for an electric furnace that does not cause thermal deformation even at high temperatures.

상기한 바와 같은 본 고안의 목적을 실현하기 위하여, 전기로 내에 다수개 배치되어 이송 수단에 실려진 부품의 온도를 용융점 이하로 가열하는 전기로 히팅 엘리먼트에 있어서, 상기한 히팅 엘리먼트는 다수개의 열선이 간격 유지구에 의해 구속되며, 이 열선의 상단부는 지지부재에 의해 구속되는 전기로용 히팅 엘리먼트를 제공한다.In order to realize the object of the present invention as described above, in the electric furnace heating element which is arranged in a plurality in the electric furnace and heats the temperature of the parts loaded on the transport means below the melting point, the heating element is a plurality of heating wires Constrained by the spacing tool, the upper end of the hot wire provides a heating element for the furnace which is constrained by the support member.

상기한 지지부재는 원판상으로 이루어지는 전기로용 히팅 엘리먼트를 제공한다.The support member provides a heating element for an electric furnace made of a disc shape.

또한 상기한 열선은 U자상으로 형성되는 전기로용 히팅 엘리먼트이며, 이 열선은 인접한 열선과 사부가 용접으로 연결되는 전기로용 히팅 엘리먼트이다.In addition, the heating wire is a heating element for the electric furnace is formed in a U-shape, this heating wire is a heating element for the electric furnace in which the adjacent heating wire and the four ends are connected by welding.

[실시예]EXAMPLE

이하 본 고안의 바람직한 실시예를 첨부한 도면을 참조하여 더욱 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in more detail.

제1도는 본 고안에 의한 히팅 엘리먼트의 사시도로서, 전원이 연결되는 커넥터 부(2)는 열선(4)의 일측단부(6)와 용접에 의해 융착되어 있다.1 is a perspective view of a heating element according to the present invention, wherein the connector portion 2 to which a power source is connected is fused by welding with one end 6 of the heating wire 4.

상기한 열선(4)은 U자상으로 이루어져 인접한 열선과 상단부가 용접에 의해 연결되므로서 상기한 일측단부(6)로 인가되는 전원은 모든 열선으로 흐를 수 있게 된다.Since the heating wire 4 is made of a U-shape, the adjacent heating wire and the upper end are connected by welding, so that the power applied to the one end 6 can flow to all the heating wires.

상기한 열선(4)은 각각 독립적으로 U자 형상으로 이루면서 상단부는 용접으로 인접한 열선과 연결되며, 몇개의 간격 유지구(8)에 지지되어 있다.The heating wires 4 are each independently U-shaped, and the upper end is connected to the adjacent heating wires by welding, and is supported by several gap holders 8.

상기한 간격 유지구(8)는 원판상으로 이루어져 상기한 열선(4)이 관통하는 구멍이 뚫려져 있다.The above-described spacing holder 8 is formed in a disc shape, and a hole through which the hot wire 4 penetrates is drilled.

이와 같이 이루어지는 열선은 상단부가 열변형을 방지하기 위한 지지부재(10)로 구속되어 있는데, 이 지지부재는 상기한 간격 유지구와 동일한 형성을 갖는다.The heating wire made in this way is constrained by the support member 10 for preventing the upper end from being deformed, and this support member has the same formation as the above-described spacer.

즉 제2도에 도시한 바와 같이 지지부재(10)는 열선(4)의 상단부를 구속하여 열변형시 전후좌우로 휘어지지 않도록 하므로서 인접한 열선과 접촉하는 것을 방지할 수 있도록 하고 있다.That is, as shown in FIG. 2, the support member 10 restrains the upper end of the heating wire 4 so as not to bend back and forth and left and right during thermal deformation, thereby preventing contact with the adjacent heating wire.

따라서 제3도에 도시한 바와 같이 전기로(12) 내에 본 고안에 의한 히팅 엘리먼트(U)가 위치되어 전원이 인가되면, 약 1000℃로 가온되는데, 이때 종래의 히팅 엘리먼트는 열선의 상단부를 지지하는 수단이 없어 열변형을 일으키지만, 본 실시예의 열선은 지지부재(10)가 구속하고 있으므로 고온시 열변형을 일으키지 않는다.Therefore, as shown in FIG. 3, when the heating element U according to the present invention is placed in the electric furnace 12 and the power is applied, the heating element is heated to about 1000 ° C. At this time, the conventional heating element supports the upper end of the heating wire. Although there is no means to cause heat deformation, the heat wire of the present embodiment does not cause heat deformation at high temperature because the support member 10 is constrained.

이상 설명한 바와 같이 본 고안에 의한 히팅 엘리먼트는, 자유단으로 존재하는 열선의 상단부를 구속하여 변형을 방지하고 있기 때문에 열선이 인접한 열선과 접촉하여 쇼트를 발생하지 않게 되며, 또 이것은 전기로 내에 이송 수단(B)에 실려져 열처리가 진행되는 부품들을 정상적으로 열처리할 수 있어 열처리 작업을 효율을 높일 수 있다.As described above, since the heating element according to the present invention restrains the upper end of the heating wire existing at the free end to prevent deformation, the heating wire does not generate a short in contact with the adjacent heating wire, and this is a transfer means in the electric furnace. Parts (B) are subjected to the heat treatment of the heat treatment is normally heat treatment can increase the efficiency of the heat treatment work.
